Description

Technical Field

[0001] The utility model relates to the technical field of battery soft packs, in particular to a battery soft pack forming device. Background Art

[0002] In modern battery packaging, soft packs are a commonly used packaging form. Battery soft packs can better match the shape of the battery compartment, and can fully play a role in lightweight applications. The material of existing battery soft packs is just a liquid lithium-ion battery covered with a polymer shell.

[0003] In the existing battery soft pack forming process, the battery electrode is mostly formed by stacking and winding, and then the battery electrode is wrapped with a polymer outer skin, and the battery soft pack is formed by stamping. However, the stamping process of the existing battery soft pack forming device mainly uses a mold that is symmetrical up and down. In the existing battery soft pack forming process, in order to facilitate the assembly of the electrode sheet, it is often placed in a slightly larger outer packaging bag. Therefore, during the forming process, the electrode sheet also needs to be positioned twice to avoid the electrode sheet from moving in the package. Otherwise, it is easy to skew during stamping, causing damage to the electrode sheet. This part is mainly completed manually, so the efficiency is relatively low. In view of this, in-depth research was conducted on the above-mentioned problems, and thus this case was created. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: in the modern battery soft pack production and molding process, the stacked and wound electrode sheets are mainly placed in a packaging paper bag. After the electrode sheets are placed in the packaging paper bag, hot pressing is required to make the packaging bag fit the electrode sheets tightly. However, when the existing battery soft pack is being molded, the electrode sheets are easily skewed when the package is placed in the mold, thereby causing the electrode sheets to be crushed during the molding of the battery soft pack.

[0022] In view of the above problems, the present application discloses a battery soft pack forming device, which uses a support frame 1 as a supporting body, and the support frame 1 is arranged on one side of a pressing device. A pusher 2 arranged on the support frame 1 can control a pushing plate 3 to move, and the battery soft pack is pushed by the pushing plate 3 to be sent into a pressing mold of the pressing device;

[0023] Furthermore, a pair of control cylinders 6 are provided on both sides of the push plate 3, and a control plate 7 is connected to the telescopic ends of the pair of control cylinders 6. The position of the control plate 7 is adjusted by the pair of control cylinders 6, and the relative distance between the control plate 7 and the push plate 3 changes under the action of the control cylinders 6, thereby realizing the control of the clamping action of the clamping device on the push plate 3 and the control plate 7;

[0024] Further, a pair of first clamping seats 4 are arranged on both sides of the push plate 3, and a pair of first finishing rollers 5 are arranged between the pair of first clamping seats 4 on the push plate 3; a pair of second clamping seats 8 are symmetrically arranged on both sides of the control plate 7, and a pair of second finishing rollers 9 are arranged between the pair of second clamping seats 8 on the control plate 7; the positions of the first clamping seat 4 and the second clamping seat 8 correspond to each other up and down, and the positions of the first finishing roller 5 and the second finishing roller 9 correspond to each other up and down;

[0025] In the specific implementation process, the first clamping seat 4 on the pushing plate 3 is opposite to the second clamping seat 8 on the control plate 7. Under the action of the control cylinder 6, the pair of first clamping seats 4 and the pair of second clamping seats 8 are opened and closed by the action of the upper and lower openings to clamp the two ends of the packaging bag, and the two sides of the packaging bag are closed by the relative clamping of the pair of first finishing rollers 5 and the pair of second finishing rollers 9.

[0026] Furthermore, it is necessary to control the positions of the first sorting roller 5 and the second sorting roller 9, and a relative limit assembly is provided on the push plate 3, and a pair of control sliders are provided on the relative limit assembly, and a single control slider is movably connected with the first sorting roller 5 and the second sorting roller 9 corresponding to the upper and lower sides of the same side. Specifically, the relative movement of the pair of control sliders is controlled by the relative limit assembly, so that the pair of first sorting rollers 5 and the pair of second sorting rollers 9 are controlled to move relative to each other by a pair of control sliders, and the first sorting roller 5 and the second sorting roller 9 are used to push the skewed electrode toward the middle, so as to ensure that the electrode sheet is in the positive direction and in the middle position.

[0027] As a preferred solution, further, a pair of first clamping seats 4 is a pair of rectangular structure plates, and the shape of a pair of second clamping seats 8 corresponds to the position of a pair of first clamping seats 4. The two ends of the packaging bag can be clamped through the relative planes of the first clamping seats 4 and the second clamping seats 8.

[0028] As a preferred solution, further, the push plate 3 and the control plate 7 are connected via a plurality of guide grooves and guide blocks to ensure stable movement of the push plate 3 and the control plate 7.

[0030] In the specific implementation process, the control motor 11 is used to drive the control screw 10 to rotate, so that the control screw 10 is threadedly engaged with the threaded holes of a pair of control sliders, thereby causing the pair of control sliders to move relative to each other, and then causing the pair of control sliders to drive the first finishing roller 5 and the second finishing roller 9 to move relative to each other.

[0031] As a preferred solution, further, a pair of control sliders are extended to one side to be provided with a pair of toggle holes 12, and the ends of the first sorting roller 5 and the second sorting roller 9 respectively pass through the pair of toggle holes 12. Specifically, the pair of toggle holes 12 are used to match and limit the ends of the first sorting roller 5 and the second sorting roller 9, so that the first sorting roller 5 and the second sorting roller 9 can drive the first sorting roller 5 and the second sorting roller 9 to move synchronously when the toggle holes 12 move, and then the toggle holes 12 are used to cooperate with the vertical activities of the first sorting roller 5 and the second sorting roller 9, and in the process of the up and down movement of the control plate 7 and the push plate 3, the movement of the second sorting roller 9 is matched to provide the second sorting roller 9 with movement space.

The movement of the pushing plate 3 is controlled by the pushing cylinder, and a pair of auxiliary slide rails 13 are provided on both sides of the pushing cylinder to stabilize the movement of the pushing plate 3.

[0033] From the above, it can be generally known that the battery soft pack forming device adopts hot pressing forming, and a clamping device with a pusher 2 is arranged on one side of the hot pressing forming device. On the one hand, the two sides of the battery soft pack packaging bag are clamped by the clamping device, and on the other hand, the outside of the soft pack is clamped by the paired first sorting roller 5 and the second sorting roller 9, and then the relative limit assembly is used to control the relative movement of the first sorting roller 5 and the second sorting roller 9, so as to push the electrode sheet in the battery soft pack to the middle of the soft pack and then send it into the pressing device to avoid the electrode sheet being skewed and crushed.
